EYEGLASSES.

SPECIFICATION forming part of Letters Patent No. 755,014, dated March22, 1904.

Application filed October 6, 1902.

To all whom it may concern:

Be it known that I, HENRY E. KIRSTEIN, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefulImprovements in Eyeglasses; and I do hereby declare the following to bea full and clear description of the same, reference being had to theaccompanying drawings, forming a part of this specification, and to thereference-numerals marked thereon.

My present invention has for its object to provide an improved mountingor frame for eyeglasses and one which embodies a novel arrangement ofthe nose guards, which are adapted to firmly engage the wearers nose andare so attached to the frame that the length of the bow-spring or bridgeis increased without detracting from its appearance to afford additionalelasticity in the spring, as well as to provide sufiicient material,whereby a frame may be capable of a wide range of adjustment when beingfitted by an Optician.

To these and other ends the invention consists in certain improvementsin construction and combinations of parts, all as will be hereinaftermore fully described, the novel features being pointed out in the claimsat the end of the specification.

In the drawings, Figure 1 is a perspective View of a pair of eyeglasses,illustrating a frame or mounting constructed in accordance with myinvention. Fig. 2 is a longitudinal sectional View thereof.

Similar reference-numerals in both figures indicate similar parts.

Eyeglasses constructed in accordance with my invention embody the lenses1, and the latter are connected by means of the saddle or band-spring52, forming the bridge-piece and preferably arranged with the centralportion at an angle to the plane of the lenses and having thelaterally-extending perforated ends 3, adapted to be secured to thelenses by suitable devices, which in the present instance are shown asscrews or rivets 4, passing through the lens-clips 5. The ends of thespring adjacent the proximate edges of the lenses are preferablyprovided with U-shaped portions or loops 6, which lie on opposite sidesof the wearers nose, forming the rearwardly-extend- Serial No. 126,003.(No model.)

ing sides, which afford sufficient length in the spring to provideconsiderable elasticity therein and at the same time providing meanswhereby the tension of the spring may be adjusted and the distancebetween the center of the lenses altered to obtain the correct pupilarydistance. The guards 7, which bear upon opposite sides of the wearersnose, are located between the arch or center of the springerbridge-piece 2 and the ends of the side portions, and they are supportedupon arms 8, curved in the present instance and preferably of springmaterial, so that the guards lie in opposition to each other and withinthe bowspring or curve of the bridge-piece, said arms being detachable,sothat different forms of guards may be employed, if desired.

I do not desire to be confined to the exact construction of the partsillustrated, as vari ous modifications of the device will be suggestedto those skilled in the art without departing from the spirit of myinvention.

The means of supporting nose-guards which I have shown and described issimple and permits any of the various shapes and sizes thereof beingemployed, and by locating them be tween the top and the loops near theends of the spring I am enabledto arrange the latter so that it may beformed to lie very close to the wearers nose as it curves over thebridge thereof andstill be of sufiicient length to afford considerableelasticity, whereby the glasses may be easily applied and when soapplied securely held in position.

While I have described the guards as applied entirely to eyeglasses, itwill of course be readily seen that they may be used with equalefficiency upon spectacles, the arms upon which they are supported, ifof elastic material, allowing the guards to give in planes parallel withthe lenses as well as those at right angles thereto.

I claim as my invention-- 1. In eyeglasses, the combination with thelenses and the bridge-spring having the substantiallyhorizontally-extending loops arranged in rear of the lenses and betweenthe center and the point of attachment to the lenses, of the yieldingguard-arms secured to the lenses at one end and having the bearinglensesat one end, thence extending in rear of 10 the loops and forwardly andhaving the bearing-pads at the free ends arranged between the rear endsof the loops of the bridge-spring and the forward portiol of saidspring.
